WARNING!
WARNING! Disconnect electrical power source to prevent
injury or death from electrical shock.
CAUTION!
CAUTION! Use only copper conductors for field installed electrical
wiring. Unit terminals are not designed to accept other types of
conductors.
Electrical - Line Voltage
All field installed wiring, including electrical ground, must
comply with the National Electrical Code as well as all
applicable local codes. Refer to the unit electrical data for
fuse sizes. Consult wiring diagram for field connections
that must be made by the installing (or electrical)
contractor. All final electrical connections must be made
with a length of flexible conduit to minimize vibration and
sound transmission to the building.
General Line Voltage Wiring
Be sure the available power is the same voltage and
phase shown on the unit serial plate. Line and low voltage
wiring must be done in accordance with local codes or the
National Electric Code, whichever is applicable.

Three phase wiring is similar except that all three
power wires are directly connected to the contactor.

Power Connection
Line voltage connection is made by connecting the
incoming line voltage wires to the "L" side of the
contractor as shown in Figure 15. Consult electrical data
tables for correct fuse size.
Transformer
All 208/230 voltage units are factory wired for 208
volt. If supply voltage is 230 volt, installer must rewire
transformer. See wire diagram for connections.
